The MYD-LPC4357 development board is among the MYD-LPC435X series designed using NXP LPC4357 32-bit ARM Cortex-M4 based microcontroller for embedded applications which includes an ARM Cortex-M0 coprocessor, up to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB of EEPROM memory, a quad SPI Flash Interface (SPIFI), advanced configurable peripherals such as the State Configurable Timer (SCT) and the Serial General Purpose I/O (SGPIO) interface, two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals. The LPC4357 operates at CPU frequencies of up to 204 MHz.

The MYD-LPC4357 board takes full features of the NXP LPC4357 ARM microcontroller and has rich peripherals including 3 UARTs, USB Host, OTG, Ethernet, 2 CAN interfaces, RS485, LCD, Audio, etc. It has external 32MB SDRAM, 2MB Nor Flash and 4MB Data Flash on board as well as one Micro SD card slot to enhance storage capabilities.

The MYD-LPC4357 board comes with sample codes bundle for the peripherals using Keil's MDK-ARM to help users evaluate the NXP LPC4357 ARM Cortex-M4 microcontroller and detailed document as well as some necessary cable accessories to help users evaluate, learning and make prototype at a fast period. The board enables customers to develop a wide range of applications such as motor control, power management, industrial automation, robotics, medical, automotive accessories, and embedded audio.
